X-rays won't harm hard drives but can damage undeveloped film
X-ray scanners at airports will not harm external or internal hard drives. They are well-shielded, and x-rays do not interfere with magnetic media. However, x-ray scanners can damage undeveloped film. The risk of damage depends on the film's ISO speed, with film above 800 ISO being more susceptible. High-speed film, multiple passes, and already-exposed film are also more likely to be affected.
Undeveloped film refers to film that has not been processed or exposed to light. It is still light-sensitive, and x-rays can cause fogging and damage to photos. This is more likely to occur with high-intensity screening technology, such as CT scanners, which are now being used for carry-on bags in some airports.
To avoid any potential damage to undeveloped film, it is recommended to request a hand inspection at the airport security checkpoint. This is usually not a problem, especially in the United States. It is also recommended to keep film out of checked baggage, as the equipment used to screen checked luggage is more powerful and can cause irreversible damage to film.
While x-rays from airport scanners are generally safe for hard drives, it is important to note that there may be other factors to consider when travelling with electronic devices. For example, some users have reported issues with airport security policies or suspicions about the hard drive being a bomb.

Hard drives don't need to be removed from bags at security
Travellers are allowed to carry portable hard drives with them on flights. They can be placed in either checked-in luggage or carry-on luggage. However, it is highly recommended to keep them in carry-on luggage as you can maintain physical possession and/or visual contact with them. This way, you can take appropriate countermeasures in case of any mishandling or damage.
Some travellers have reported that their portable hard drives have been scanned by airport security without any issues. However, others have reported that their hard drives have been inspected manually during hand searches by security. In rare cases, border agents may keep your belongings, including your hard drive, without any particular reason. Therefore, it is advisable to back up your data before travelling.
Airport X-ray machines are not known to harm hard drives. Nevertheless, it is worth noting that security personnel may request to inspect the contents of your hard drive, especially if your job involves handling confidential information. Thus, it is essential to be aware of the legislation and your rights regarding data privacy and protection in the country you are travelling to.
Additionally, the requirement to remove laptops, tablets, and hard drives from bags during security checks varies depending on the airport. Some airports require laptops to be removed from bags, while tablets and external hard drives can remain inside.

Laptops must be removed from bags, but tablets can stay
When going through airport security, travellers must subject themselves to various procedures in the name of safety. One such procedure is removing laptops from bags before passing through security. However, tablets and external hard drives can remain in the bag.
The TSA Blog states that laptops must be removed from bags at security, while tablets and external hard drives can stay. This is a standard security procedure at most airports. Travellers should be prepared to remove their laptops from their bags before passing through security.
It is worth noting that there may be exceptions to this rule at certain airports. Some travellers have reported that they are not required to remove their laptops from their bags at specific airports. Therefore, it is essential to check the requirements of the specific airport before travelling.
While laptops must be removed from bags, it is recommended that external hard drives be carried in hand luggage. This is because checked baggage is routinely X-rayed and searched without the owner's knowledge. By carrying external hard drives in hand luggage, travellers can maintain physical possession and visual contact with their devices.
Additionally, airport X-ray machines are not known to harm hard drives. However, it is worth noting that border agents may inspect electronic devices and potentially keep them without any particular reason. Therefore, travellers should be aware of the potential risks of carrying sensitive data across borders. Overall, when passing through airport security, travellers should be prepared to remove their laptops from their bags, while tablets and external hard drives can remain in the bag.

Border agents can keep your devices without reason
Portable hard drives are allowed to go through airport security. However, it is recommended to carry them in your hand luggage, as checked luggage is routinely X-rayed and searched without your knowledge. X-ray machines at the airport are not powerful enough to harm hard drives.
Border agents have the authority to search electronic devices at the border, regardless of your legal status or whether they suspect you of committing a crime. While you can state that you do not consent to a search, this will likely not prevent Customs and Border Protection (CBP) agents from taking your device. They might conduct a "basic search" on the spot, or download and save your data for a more thorough "advanced" or "forensic" search.
CBP agents are required to follow certain procedures before searching attorney-client or attorney work product materials. If you possess such information, you should inform the agent before the search begins. Journalists carrying sensitive information are also insufficiently protected, and it is unclear how CBP directives apply to them.
To ensure compliance with this policy, keep your devices in airplane mode and store sensitive data in a secure cloud-storage account. You can also encrypt your devices with strong and unique passwords and shut them down when crossing the border. If you leave the border checkpoint without your device, make sure to get a receipt with information about your device and contact details for follow-up.
While the number of travelers whose electronic devices are searched is small (less than 0.01% in FY 2024), it is important to be aware of your rights and take precautions to protect your data.

Avoid putting hard drives in checked luggage
It is advisable to avoid putting hard drives in checked luggage for several reasons. Firstly, there is a risk of theft or damage to the hard drive. Checked luggage is often handled roughly and may be subjected to higher levels of scrutiny by airport security, increasing the chances of your hard drive being damaged or lost. In the event that your checked luggage is lost or delayed, you may be left without access to your important data for several days.
Secondly, from a security standpoint, it is crucial to maintain physical possession and visual contact with your hard drive at all times. If your hard drive is in your checked luggage, you cannot guarantee its safety or ensure that it has not been tampered with. There have been reports of border agents confiscating electronic devices without any particular reason, and checked baggage is routinely x-rayed and searched without your knowledge. By keeping your hard drive with you in your carry-on luggage, you can better protect your data and take appropriate countermeasures if any issues arise.
Additionally, while the risk is low, there is a possibility that airport X-ray machines could potentially damage your hard drive. Although X-rays are generally considered safe for electronic devices, some travellers have expressed concerns about the potential impact of high-energy photon rays on sensitive hard drives. To mitigate this risk, it is advisable to keep your hard drive with you and request a manual inspection if necessary.
Furthermore, it is essential to consider the potential consequences of losing your hard drive or having it compromised. If your hard drive contains personal or confidential information, putting it in checked luggage may expose you to identity theft or data breaches. In today's digital age, protecting your data is of utmost importance, and travelling with your hard drive in your carry-on luggage allows you to take responsibility for its safety and security.
Lastly, in the event that you need to access your data during your flight or immediately upon arrival, having your hard drive in your carry-on luggage provides easy access. Whether you need to retrieve important documents, work on a project, or simply access personal files, having your hard drive within reach can make your travel experience more convenient and efficient. Therefore, it is highly recommended to avoid placing hard drives in checked luggage and instead carry them with you during your journey.
